DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller for a water heater used at home.

[0002]

2. Description of the Related Art As shown in FIG. 2, a remote controller used for a water heater is sold with a bathroom remote controller 21 and a kitchen remote controller 22 attached to a main body 23, and an additional remote controller 24 is sold separately. Use in washrooms other than bathrooms and shower rooms
In general, an additional remote control for use has exactly the same specifications as a kitchen remote control. Also priority
A priority button for switching circuits is provided on the bathroom remote control,
When using a shower in the bathroom, the priority circuit
Switch to the computer side to ensure safety
Was.

[0003]

However, in such a conventional method, when an additional remote controller is used, the temperature setting is changed at two places when the priority circuit is switched to the kitchen remote controller or the additional remote controller. There was a problem that the temperature of the hot water was suddenly set by the additional remote control while hot water was being used in the kitchen and the temperature of the hot water suddenly increased, thereby increasing the chances of burns.

[0004] The present invention ensures the safety in the bathroom as before.
It is another object of the present invention to solve the above-mentioned problems and to provide a safe water heater.

[0005]

In order to achieve the above object, the present invention has a remote controller for bathroom, a remote controller for kitchen, a remote controller for kitchen, and an extension remote controller having the same priority circuit for setting hot water supply temperature. The remote control has a hot water supply temperature setting switch, and the bathroom remote control switches the priority circuit.
In the apparatus having a front button, the upper limit of the hot water temperature setting of the extension remote controller is set lower than the upper limit of the hot water temperature setting of the bathroom remote controller and the kitchen remote controller.

[0006]

According to the present invention, it is possible to prevent the setting of a high temperature by using the additional remote controller while using hot water in the kitchen.
The remote control for extension
In no danger such as accidentally burns out high-temperature hot water.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a water heater 1 is connected to a bathroom remote controller 2, a kitchen remote controller 3, and an additional remote controller 4 having the same priority circuit for setting the kitchen remote controller and hot water temperature. The hot water supply temperature setting of the bathroom remote controller 2 and the kitchen remote controller 3 is set between 38 ° C. and 47 ° C. in steps of 1 ° C., and further set at 55 ° C. and 65 ° C. On the other hand, the extension remote controller has a hot water supply temperature setting of only 38 ° C to 47 ° C.

While the hot water supply temperature cannot be changed with the bathroom remote control 2 while hot water is being used in the kitchen, the kitchen remote control 3 cannot be used.
When the hot water temperature setting switch 5 of the additional remote control 4 is consciously or erroneously operated, the temperature of the hot water in the kitchen changes, but at most 47 ° C. There is no danger of getting burned.

In particular, since the additional remote controller 4 is often installed in a washroom or a bedroom on the second floor, it is expected that a child or an elderly person may operate the remote controller by mistake. It can eliminate such dangers. On the other hand, when hot water is used in the bathroom, pressing the priority button 6 of the bathroom remote control 2 is safe because other remote controls cannot change the hot water supply temperature setting. Conversely, if the operation switch 7 of the kitchen remote control 3 is turned on and off, priority is given to the kitchen remote control 3 and if hot water is used in the kitchen,
There is no danger that the hot water temperature setting can be changed by the bathroom remote controller 2.

[0010]

As is apparent from the above embodiments, the remote controller for bathroom and the remote controller for kitchen, the remote controller for kitchen and the priority circuit for setting the hot water supply temperature according to the present invention can be used as an additional remote controller.
Priority button that switches the priority circuit to the bathroom remote control
In each of the remote controllers that have a hot water temperature setting switch in each remote controller, the upper limit of the hot water temperature setting of the remote controller for extension is set lower than the upper limit of the hot water temperature setting of the remote controller for bathroom and kitchen . Even if you change the hot water temperature setting of the extension remote control by mistake while using hot water in the kitchen, there is no danger of burns such as hot water.
